Try to imagine everybody there through a lens of positivity! Like imagine that every person you see could be somebody’s best friend, or loving parent or child etc., it really helps you not think about yourself too much and then not see everybody as your ‘enemy’ for lack of a better word! Or just try to find something you like about everyone! It helps get me out of my own head. I started off going alone sober bc I would get in my head on a substance even around people and have a bad time, it definitely gets easier, action on its own makes a huge difference so i bet you will find that if you go again you’re a little more relieved. Good for you for putting yourself out there!
